How to Price a Cosmetic Part When You Normally Quote Brackets
September 12, 2026
A front panel looks like a flat plate with holes in it. Quoted as a flat plate with holes in it, it loses money, and the loss does not show up until the batch is rejected on appearance and somebody has to decide who pays.
This is written for shops that quote industrial work well and are looking at cosmetic work for the first time.
What is different
On an industrial part, the quote is roughly material plus setup plus cycle time plus a margin. Inspection is dimensional, handling is whatever the shop normally does, and a scratch is not a defect.
On a cosmetic part, three things change:
- The part can be dimensionally perfect and still be rejected. Appearance is a specification you either control or gamble on.
- Most of the added cost is per piece, not per order. Deburr, handle, inspect and pack are repeated for every part, so they do not spread with quantity the way setup does.
- Scrap is a real line. Some percentage will be rejected at final inspection, and on a rework you pay twice: strip, refinish, or remake.
Build the quote in lines
Quote it the way it actually happens, not as a multiplier.
| Line | How to estimate |
|---|---|
| Material | Normal, plus offcut. Note whether the alloy is a special order |
| Programming and fixture | Once per order. Fixtures for cosmetic parts often need soft jaws or vacuum to avoid marking |
| Machining cycle | Normal |
| Deburr and surface preparation | Minutes per part times quantity. Time one, do not guess |
| Finishing | Usually a minimum charge plus a per part rate. Get it from the finisher before quoting |
| Cosmetic inspection | Minutes per part, per cosmetic face, under proper light |
| Scrap allowance | A percentage of machining plus finishing, from your own history |
| Packing | Individual bagging, film, trays. Minutes per part plus consumables |
| First article | A setup, a few pieces and one finishing cycle. Quote it separately |
The two lines general shops leave out entirely are cosmetic inspection and scrap allowance. They are also usually the difference between a profitable cosmetic job and a painful one.
Fixturing costs more than you think
A cosmetic part cannot be gripped the way an industrial part can.
- Hard jaws mark the workpiece. Soft jaws, vacuum or a sacrificial layer are normal, and they take time to make.
- A part finished on five faces needs a fixture that holds it without touching the sixth.
- Parts cannot be dropped into a bin between operations, so material handling between ops takes longer.
Put fixture making in the quote as real hours. Trying to absorb it is how a first cosmetic job goes wrong quietly.
Read the drawing for the risk, not just the geometry
Before pricing, look for these. Each one changes the number.
- How many faces are cosmetic? One face is manageable. Five faces means the part can be damaged at almost any point in the route.
- What finish? Clear anodize on 6061 shows everything. Bead blast then black anodize hides a lot. A mirror polish is the highest risk finish in common use.
- Is there a colour to match? Matching an existing part is a different job from producing a colour. If there is no physical reference sample, that is a question, not an assumption.
- Is the part one of a matched set? If four knobs have to match, a single bad one scraps the set.
- Is the rack point specified? If not, ask. If you pick wrong, you own the rejection.
- Is there a written acceptance criterion? Viewing distance, light, time. If the drawing says “no visible defects” with nothing else, that is unpriceable and you should say so.
Questions worth asking before you quote
Asking these does not make you look uncertain. It marks you as a shop that has done this before, and buyers notice.
- Which faces are cosmetic, and which are not?
- Is there a reference sample, or is this the first article that creates one?
- What is the acceptance criterion: distance, light, time?
- Where may the rack point go?
- Is this part matched to another part?
- What is the annual volume, not just this order?
- Who owns the finishing, and can I use my own finisher?
- How should it be packed, and who pays if it arrives marked?
If a buyer cannot answer most of these, the drawing is not ready and the quote will be a guess. Saying so politely is better business than quoting low and arguing later.
Where to be honest rather than optimistic
Two situations where declining is the right commercial answer:
Colour matching an existing part with no physical reference. You cannot promise it and nobody can. Say you will produce a sample and let the buyer judge it, and price the sample round.
A finish you have not run before, on a deadline. The first batch through any new finish route has a learning cost. Taking that on someone else’s tight deadline means the learning cost lands as a late delivery.
A shop that declines these gets asked again. A shop that quotes them and misses does not.
The commercial argument for doing it anyway
Cosmetic work is harder to quote, and that is exactly why it is worth having.
- Fewer shops can do it, so there is less price pressure
- Buyers who find a shop that can repeat a finish do not go shopping again every year
- Repeat cosmetic work is high margin once the fixtures and the finisher are dialled in
- The same discipline, handling, inspection and packing, makes the rest of the shop better
The barrier is not machining capability. It is the bench, the finishing relationship and the willingness to put appearance on the quote as a real cost.
Frequently asked questions
How much should I add for cosmetic work?
There is no percentage that works, because the cost is not proportional to the machining. It is proportional to part count, number of cosmetic faces and how unforgiving the finish is. Build it up as real lines: deburr minutes per part, inspection minutes per part, a scrap allowance and the finishing minimum. A multiplier on the machining price will be wrong in both directions.
What scrap rate should I assume on anodized cosmetic parts?
Ask your own finisher and your own bench, because it depends on your handling more than on the part. What matters is that the number is not zero and that it is in the quote. A shop quoting cosmetic anodize with no scrap allowance is absorbing the risk silently and will lose money on the first rejected batch.
Should I quote finishing as a separate line?
Yes, and show it. Buyers who understand cosmetic work want to see it, because it tells them you priced the job rather than guessing. Buyers who do not understand it will ask, which gives you the conversation that qualifies them.
